Abstract
As mm-wave offers broader spectra and proportionate capacity increase, it will be extensively employed in 5G-and-beyond communication systems to address the exponentially growing data-rate demand. Viable mm-wave TX or PA solutions should handle multi-Gbit/s complex modulations with large PAPR, pushing the already stringent linearity-efficiency requirement on deployed TXs/PAs. This demand has stimulated extensive research on new TX/PA architectures to further advance the performance envelope at mm-wave.
